I guess this is related to the ATA - HDD matching problem some users have been experiencing since 5.3-RELEASE - Errors look similar. Briefly: System unstable when ATA controller - HDD UDMA mismatched. e.g.: UDMA 66 controller & UDMA 100 HDDrive. Late model Seagate drives can be configured to use lower UDMA access using their uata100d.exe utility (used it, myself). Don't know if other brands have a similar utility though. Hope this gets fixed before 5.4-RELEASE. Dennis On Monday 14 March 2005 04:07, Oleg V.
